Maintain Alternates

Explanation

This activity is used to define alternates or maintain the definition of alternates that are introduced to a template structure by a modification. A modification may introduce a new template alternate, a position alternate or it may require a change to the interchangeability code of an existing alternate.

Prerequisites

• The modification revision must have been created. This modification must be in the Preliminary status.
• The template structure must have been created.

System Effects

• Information on new alternates or the changes to existing alternates is registered on the modification. When the modification is activated, these alternates can be used for serials.
• If the Allow Alternate Without Modification Compliance check box is selected, the alternate definition will be effective for all serials without having to comply with the modification.
